   An update that fixes three vulnerabilities is now available.

Description:


   This update for ghostscript-library fixes the following issues:

   - Multiple security vulnerabilities have been discovered where
     ghostscript's "-dsafer" flag did not provide sufficient protection
     against unintended access to the file system. Thus, a machine that would
     process a specially crafted Postscript file would potentially leak
     sensitive information to an attacker. (CVE-2013-5653, bsc#1001951)

   - An incorrect reference count was found in .setdevice. This issue lead to
     a use-after-free scenario, which could have been exploited for
     denial-of-service or, possibly, arbitrary code execution attacks.
     (CVE-2016-7978, bsc#1001951)

   - Insufficient validation of the type of input in .initialize_dsc_parser
     used to allow remote code execution. (CVE-2016-7979, bsc#1001951)
